[0002] Hot forging is a metalworking process in which the metal is heated at high temperature to sufficient plasticity, and then formed into the desired shape by pressure or impact. This process is usually carried out at about 70% to 90% of the metal's melting point to ensure that the material is sufficiently deformable. Hot forging is often used to manufacture high-strength, high-quality, and complex-shaped metal parts. It can increase the density and mechanical properties of the metal and eliminate internal defects. Common hot forging processes include hammer forging, press forging, and extrusion forging;
